Specification of Letters Patent.

Patented Jan. 25, 1916.

To all whom it may concern:

Be it known that I, 'JAMEs E. CLENNY, a citizen of the United States, residing at Chicago,'in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Packing and Shipping Boxes, of which the following is a specification.

My invention relates to boxes made of paper board, preferably double-faced corrugated .paper board, and intended for the packaging and shipping of difierent articles.

The ob ect of my invention isto producea novel and simple construction ,of box particularly adapted for the shipment of liquid articles contained in bottles and the like and designed to comply with the rigid requirements of railroads and other transportation companies.

My shipping box is characterized by the provision of fillers and a waterproofed inner shell, the filler being made of wood or like material whichis incapable of being destroyed or weakened by liquid in caseany one of the bottles should become broken or in case of leakage. The inner shell or box being waterproofed prevents the escape of the liquid and moreoverthe corrugated paper board, of which I prefer to make such shell, is adapted to absorb on its inner side any liquid which may thus be within the inner shell. I also contemplate employing a pad on the bottom of the box for absorbing such liquid and also a top closure which is waterproofed only as to its outer side and which when in position is adapted to complete the sealing of such shell which is otherwise made of a single piece.

In the use of paper board for packing and shipping boxes, particularly as a substitute for wooden boxes, objection has been made by railroads and other transportation.

companies especially as regardsthe shipping of liquids in bottles, the bottles being liable to become broken and the contents being liable to'leak from the box to the damage of other goods and to also destroy or weaken the box itself. Moreover, when fillers of paper board are used the liquid absorbed by such filler is liable to destroy its strength or so weaken it that the other bottles contained in the box will strike each other and cause further breakage. The object of my present invention is to overcome these difficulties and objections by providing a packing or shipping box in which any liquid from broken bottles is retained in the box and this without destroying or weakening it or any of its parts, including the filler, which is made of material other than the usual paper board, such as wood.

In the drawing Figure 1 is a perspective of my box with the outer shell opened out and with the closure of the inner shell removed; Fig. 2 a cross section of the box in closed condition but on a larger scale than in Fig. 1; Fig. 3 a detail perspective view of one of the corners of the inner shell; Fig. 4 a sectional plan of one of the corners of the inner shell; Fig. 5 a sectional detail on the line 5-5 of Fig. 4. and Fig. 6 a detail view of a modified form of construction.

I prefer to make the entire box with the exception .of the filler of double face corrugated paper board, but in the broader aspect of my invention this is not essential particularly as to the inner shell, which, as shown in Fig. 6 might be made of sin le face corrugated paper board as hereina ter explained.

Referring to Figs. 1 to 5 the box proper comprises two main parts, to wit an outer box or shell and an inner box or shell. The outer shell which may be of any suitable proportions and dimensions is provided with four side walls 1, whose upper and lower edges are provided with the extensions 2, which latter when folded inwardly and downwardly constitute the top and bottom closures of the entire box. After these closures have been thus folded the box may be sealed over the joint in suitable manner as by means of the sealing tape 3, Fig. 2.

The inner shell is made from a single piece of paperboard which in the present instance is double faced corrugated paper board. As shown this inner shell comprises a bottom 4:, and four side walls 5 hinged thereto and corresponding substantially in size with the side walls 1 of the outer shell and in addition such inner shell comprises the triangular corner folds 6 which are folded upon each other and against the outer faces of two of the opposite side walls of the inner :shell. By preference the corrugated character of these corner folds is destroyed by crushing down the corrugations thereof thereby permitting easier folding of these corner folds and narrowing the space between the inner and outer shells. In order partments or pockets and made of wood or to hold these corner folds in place and secure them to their side walls suitable means may be employed, as for instance the hook 7, one

arm of which is passeddownwardly in the corrugations of the side wall and the other. arm of which is passed downwardly through preference the remainder of the paper board ,materiahthatis the inner facing strip and the corrugated strip, are left in their usual condition, with the result that they are capable of absorbing any liquid within the shell and of thereby acting'as a sponge. If desired the pad which may also ,be made of double faced corrugated paper board or of the single faced variety but not waterproofed, may be used in the bottom of the inner shell for the special purpose of absorbing any liquid from the bottles, such a Brad geing indicated in the drawing at 8,

Within the inner shell is arranged the filler 9 having any suitable number of comany other. rigid material incapable of being destroyed or weakened by liquid, so that in case of the breakage of one bottle the other bottles would not be liable to come, in contact with each other, the wood maintaining under all conditions the proper relative position and spacing of the bottles. 7

Boxes containing liquids in glass are generally marked to indicate which side should be kept up so that theoretically it would be unnecessary to provide any closure for the top of the inner shell, but asin practice the directions on the box are not always observed by the persons handling the boxes intransit, I prefer to provide a closure which not only closes but seals the top of the inner shell. For this purpose I employ a sheet 10 of double faced corrugated paper board which is water proofed on that side exposed to the interior of the inner shell. This closure is provided with marginal extensions 11 which are tucked downwardly between the side walls of the inner and outer shells, Fig. 2.

I Fig. 6 I have shown a modified form of construction according to which the inner shell instead of being made of double faced corrugated paper board is made of the 7' faced variety, such single faced paper being indicated at 12.
